Impact of environmental radiation on the health and reproductive status of fish from Chernobyl, Ukraine 2014 to 2015

Data comprise health, reproductive status and relative abundance of mature perch and roach collected in September 2014, March 2015, June 2015 and September 2015 from lakes in Belarus and Ukraine. Measurements presented include age, weight, length, presence of external signs of disease and presence of macroscopic tumors. The Fulton condition index (K), hepatosomatic index (HSI) and gonadosomatic index (GSI) of fish are also presented. The lakes (selected according to hydrological properties and long-term exposure to a gradient of radiation dose) are situated at distances from 1.5 to 225 km of the Chernobyl NPP. Glubokoye, Yanovsky lakes and Cooling Pond are the high (H) contaminated lakes, Svyatoye Lake is a medium (M) contaminated lake, and Stoyacheye, Dvoriche and Gorova lakes are the low (L) contaminated lakes.

本数据集收录了于2014年9月、2015年3月、2015年6月及2015年9月，在白俄罗斯和乌克兰湖泊中采集的成熟鲈鱼和鳊鱼的卫生健康状况、繁殖状态及相对丰度。其中所展示的测量指标包括年龄、体重、长度、外部疾病症状的呈现情况以及宏观肿瘤的存在情况。此外，还提供了鱼类的水福顿条件指数（K）、肝脏组织指数（HSI）和生殖组织指数（GSI）。所选湖泊根据水文特性和长期暴露于辐射剂量梯度的情况进行选择，距离切尔诺贝利核电站1.5至225公里不等。Glubokoye、Yanovsky湖泊及冷却池塘为高（H）污染湖泊，Svyatoye湖泊为中等（M）污染湖泊，而Stoyacheye、Dvoriche和Gorova湖泊为低（L）污染湖泊。关于本数据集的详细信息可参见https://doi.org/10.5285/02a53248-1bfd-4f1e-8f76-888551635c98。
